In this study, we analyzed the regeneration kinetics and the reversibility of the 2.3-DPG reduction in stored red cells after transfusion. Within 3 h after transfusion the 2.3-DPG levels raised up to 40% of the patients' prior 2.3-DPG concentration, although the 2.3-DPG content of the transfused red cells was less than 10% of before. The complete regeneration of the 2.3-DPG concentration occurred after 36 to 48 h after transfusion. There was a close correlation of the results obtained by P-31-NMR and enzymatic determination of DPG.

D019794 2,3-Diphosphoglycerate A highly anionic organic phosphate which is present in human red blood cells at about the same molar ratio as hemoglobin. It binds to deoxyhemoglobin but not the oxygenated form, therefore diminishing the oxygen affinity of hemoglobin. This is essential in enabling hemoglobin to unload oxygen in tissue capillaries. It is also an intermediate in the conversion of 3-phosphoglycerate to 2-phosphoglycerate by phosphoglycerate mutase (EC 5.4.2.1).
